Mousetrap car!

Building a Mousetrap Car

My partner and I had no idea how to build a mousetrap car so we looked up some videos on the internet and found this tutorial that was really helpful on understanding what we had to do. One interesting thing about the mousetrap car on the video is that the frame is the mousetrap! My partner and I thought that might be a really good idea to not use a frame so the car would be lighter. We plan to follow the video but make a few adjustments. We are going to start with the eye-hooks and the wheels from toy car seemed to work pretty effectively. Extending the lever was also something we saw be done on every video about mousetraps so we plan to do that too. The one thing we did not like about the way the car from the video bellow was built was that the wheels could move from left to right and that can cause  the car to curve. To solve this problem we thought that we could maybe use zip ties on each side to keep the wheel from shifting without stopping them to turn. So our plan step by step is:

1. Buy eye-hooks, rubber bands, wood stick, two toy cars (with different sizes of wheels) and zip ties;
2. Unlock the mousetrap;
3. Lengthen the lever with the wood stick and attached with three zip ties;
4. Make a whole on the sides of the mousetrap with a pin and place the eye-hooks on the wholes;
5. Take the wheels out of the toy cars and put the larger wheels though the eye-hooks on the back side of the car and the small one in front;
6. Fix the wheels with a zip tie on each side of the wheels so that it wont move side to side and put the rubber bands around each tire;
7. Attach the string;
8. Win the race!!!
